Speoication of Letters Patent.

Patented July 26, 1910.

Application led June 28, 1309. Serial No. 504,752.

To all whom t may concern:

Be it known that 1, RICHARD RAINns, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Machine-Guns; and

lire and also operated to fire projectiles at one spot.

Another object is the rovision of an' improved form of cartri ge tray which is adapted to feed cartridges to a cylinder and in position to be fired.

A further object is the provision of an improved form of Contact closer which is adapted to close the circuit between a' battery and a cartridge when the latter is in position to be fired.

lVith these and-other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustratedin the accompanying drawings and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invenL tion.

In the accompanying drawings forming part of the specification: side elevation ot' the device. Fig. 2 is a longitudinal sectional view of the saaie. Fig. 3 is a plan view and showinr the position of the parts when the cartridges are to be Fig. 4 is a si1nilar view but showging thc posvion of the parts when the device is to be operated for fau tire. Fig. 5 is a sectional end elevation taken on the line 5*5 of Fig. 4.

.Similar numerals of reference are employed to designate corresponding parts throughout.

The mount upon which the device is Figure 1 is a.

i placed is designated by the numeral 5 and is of a well known type having at its upper end the usual vertical extending openings for the reception of the swivel pin 6 to which the gun is secured. The barrel of the latter is designated by the numeral 7 and the stock by the numeral 8. The forward end of the latter is rabbeted as shown at 9 to provide the usual fiat support for the rear end of the barrel 7. The rear end of the barrel 7 is spaced from the rear end of the rabbeted portion 9 for a considerable distance, and into the space between the rear end of the barrel 7 and rear end of the rabbet is disposed what will subsequently betermed a cartridge carrier or tray 10. The latter j faces being provided with a plurality of car-jv tridge grooves 11. The latter converge toward the forward edge of the plate and are semi-circular in cross section and of a depthequal to one-half the diameter of the cartridge to be employed, or substantially so.

By referring now to the drawings it will be seen that the barrel 7 is swivcled on the stock 8 by means of a collar 12,. the latter being provided on its lower' side with a `depending lug 13 which lits into a socket 14. formed at the forward end of-the stock. That portion of the latter underlying the rabbet 9 is transversely recessed as shown at 15, the recess extending from a point adjacent the rear 'end of the rabbet 9 and terminating in the socket 14. Connection between'the lug 13 of the collar 12 and rear end wall of the socket is established b vl means of a pair of links 16 and 17. The forward section of these links has its for- Ward end fixedly secured to the lug 13 and its rear end terminates in a pair of jaws 18. The rear section 17 is preferably formed of a single piece of resilient metal. the iu- 'termediate portion of which is coiled or twisted so as to provide a retraetile spring 20, one terminal of which is pivoted between the jaws 18 and the opposite terminal ofI right or left the links 16 and 17 will be` Vrocked as shown in Fig. 3, whereby the `spring will be placed under-tension so that the'barrel and rabbet 9 and connection beshown at 28. j

Rising from the upper side and disposedv tweenfthe cartridge tray and barrel is established by means ofv a pair of brace rods 22 and 23, the inner ends of which are pivoted on the lug 13 of the collar 12 and the outer ends of which are fixedly secured to the forward edge and adjacent the opposite ends ofthe tray. Thus it will be seen when the stock is held stationary and it is desired to move the trayr 10 to the right the same can be done by the operator pressing on one end of the tray which will force the latter to the position shown in Fig. 3. It will be observed that the rear or conveX edge of the vcartridge tray is provided with a vertical wall 25. This member is preferably of metal andlv is insulated from the tray' by a strip of insulating material designated by the numeral 26 (Fig. 5), the

`Wall 25 is medially provided with a' plurality of spaced-openings 27, thev walls of which are flared as shown in .Fig-2. These openings correspond with the cartridge grooves 11 formed in the upper face of .the plate and the s aces between the openings 27'are insulate .with suitable material as at .the rear end of the barrelis what will subsequently be termed a circuit closer. This member 'is substantially U shaped having one of its limbs 29 xedly secured tothe upper side and at the rear end of the barrel 7 while its opposite'limb 30 extends into the space between the Verticalwall 25 "and'rear end of the rabbet 9. The end portion of the limb 30 is reduced in thickness and constitutes a'spring arm 31, the end portion of which is bent forwardly and at rightangles as shown at 32 and is disposed in a plane with the openings 27 of the ver-l tical wall 25. The bent portion 32 of the Aspring arm `normally projects through the o ening 27 with which it alines as clearly s own in Fig. 2 and in position to bear on the contact button of the cartridge.4

Journaled in the middle portion of the limbs 29 'and 30 are theopposite ends of a shaftl33.and keyedv to the shaft 33 and disposed between the limbs 29 and 30 is what .will subsequentlybe termed a cartridge cyl-y inder 34, the outer face of which is provided with av plurality of cartridge grooves 35. The latter are spacedapart for a distance corresponding exactly to thev spaces between 'the cartridge grooves 11 in the plate 10 and like the latter are semi-circular in cross sect1on and of a 'depth ual to one halfythe diameter of the cartri ge to be used. The

cartridge Acylinder is so arranged that when turned the lower-most of the grooves 35 will be coincident with the upper half of the bore of thebarrel 7 and it might be here stated, that the grooves 1l when brought into alinement with the boreof the barrel will be coincident with the lower half of the flatter, whereby the grooves 11 and 34 will coperate and'present a cylindrical opening tridge being providedwith'a Contact but-v ton which is adapted 4to be engagedv by the arm 32 of the circuit closer and when so -arranged a spark will beproduced in 'the interior yof the shell whichv will ignite the powder. This particular shell forms no part in the invention and.a is"sho-511;y merely for purposes" of illustration,' -in; order to produce a vcurrent of electrieityfwhich will op-v erate tofignite the -powder the followiltg construction "is 'i employed :-.-By referring now to F ig. 52j it will be seenv thatlocated in the butt of'thestock .area pair 4of batteries 3,(:3v which are connected in series and formed in fthe butt and adjacent the batteries is a recess 3 7. In the recess 37 is one end ofI a contactl plate 38, the outer face of which isv provided with a shank 39 terminating in va button 40; A spring arm 41 has" one end secured to the forward vend wall of therecess 4and its free end over-lies and is lspaced from the free end of the plate 38.

A spark coil 42 is located` on the lower side of the stock and adjacent the forward end thereof. A'conductin'g wire 43 has one ter-v minal connected with one pole of the batf tery and its opposite `terminal connected lwith a bindingscrew 44 on the plate 38, a

second conducting wire 45 has one terminal secured to the arm 41 overlying the free end of the plate 38 and its opposite terminal connected to one terminal of the sparker 42.

lThe opposite terminal of the sparker andthe cartridge tray are connected by means of a conducting Wire 46, the opposite terminal of the battery 36 and spring arm 31 are connected by means of a conducting wire 47, one end of which is secured to the binding post on the battery and the opposite end to a binding post 48 on the spring arm 31.

In the operation of the device the cartridges before described, are placed in the grooves 11 of the tray' 10 and when it is desired to use thedevice for straight fire the tray 10 is moved until the cartridge at one end of the tray is in alinement with the lbore ofthe barrel as before described. Vhen the parts are in this position the Contact finger 32' will bear on the contact battery and cartridge will be closed, wherecartridge.

by the spark within thelatter will ignite thepowder and the projectile will be expelled -from the barrel as before described. Whenv this has been done the cartridge tray may be moved to bring the next cartridge into alinement with the bore of the barrel, whereby the cartridge cylinder will be turned so as to bring the next groove over the It will be observed during this movement, owing tov the-ared wall ofthe opening 27 in the wall 25, that little diii- 'culty will be experienced' in turning the cartridge tray. It will be further observed when the cartridge tray has been turned sufliciently far to force the end 32 out of the opening 27 that the circuit between the cartridge and battery will be open, dueA to theinsulation 28 between the opening 27. During this movement of the cartridge tray the push button 40 may be held compressed so that when the tray has been moved sufficiently far to permit the end 32 to enter the next opening the circuit between the cartridge and battery willbe-imme'diately closed. Thus it can be seen that the device may be fired with great rapidity-and with the aid of an extra operator the cartridges may be fed to the tray practically as fast as used. A

In the use of the device for fan fire vthe operation is similar to that just described with the vexception that the tray l0 is held stationarv whilethe barrel and cylinder are rotated over the face of the tray. It is to lbe understood that the barrel 7 will be covered with .a suitable water jacket in order to keep the barrel in a comparatively cool state. l K Thus itcan be seen that I have providedl a' device which is exceedingly simple in structure and comparatively inexpensive to manufacture, embodying few parts and.

these so arranged that the danger of derangement will be reduced to a minimum.

Having thus described my invention. what y is claimed as new, is

. `1. In a machine gun the combination-with a barrel; of a rotatable cartridge cylinder carried by the barrel and exteriorly rovided with a-plurality of spaced cartridge grooves, and a feed plate provided with a plurality ofy spaced cartridge grooves each of which cooperates with a -groove of the cylinder to form a cylindrical opening in axial alinement with the bore of the barrel. 2.
